FIELD OF THE INVENTION

This invention is related to the field of interactive multimediaservices and is related more particularly to provision of interactivemultimedia programs.

BACKGROUND OF THE INVENTION

In general, presentation of multimedia programs is a passive activityfrom the viewpoint of the user. That is, not only is the content of amultimedia program typically static, but the order in which the contentis presented is also static. However, most users are typicallyinterested in obtaining additional content associated with a multimediapresentation. Unfortunately, such additional content is generally notavailable from the multimedia program itself, and users typically mustengage in independent research to uncover such content. Some multimediaprograms do provide a user with a prompt during presentation of amultimedia program. Such a prompt can lead a user to a location ofadditional content, but in doing so, the prompt generally guides theuser away from the multimedia program. Furthermore, the content providedby such prompts typically pertains only to specific, limited content atspecific points in the multimedia program.

DETAILED DESCRIPTION

Typically, when presenting a multimedia program, once the user hasselected a program for presentation, the interaction between the userand multimedia program is ended. That is, the user usually cannot obtainadditional information regarding the content of the program from theprogram itself. In some cases, such as when viewing programs usinginteractive program guide services, the user can obtain title, date, andparticipant information. Sometimes the user can also obtain a synopsis.However, the user is generally precluded from obtaining any additionalcontent. For example, a user viewing a nature documentary cannot obtainprecise location information about the images being displayed, otherthan that provided by the narrative.

According to another example, a user listening to a radio broadcast ofan opera may be able to obtain basic title, singer, venue, arrangerinformation, but cannot retrieve any type of biographical information.These types of limitations on the presentation of multimedia content aregenerally due to the fact that multimedia programs are not onlytypically presented in a linear fashion, but are time-limited as well.As a result of these limitations, producers of such programs typicallyhave to cut or exclude content and information, including content orinformation which may be of interest to at least some users.

Many users may be dissatisfied with the limited amount of contentprovided during presentation of a multimedia program. For example,referring back to the nature documentary example, a user who is planninga trip to the locations shown in the documentary may wish to obtainprecise geographic coordinates of a location or contact information forpersons interviewed. Although users can obtain the same content orinformation via alternate channels, such as the Internet, doing sotypically requires additional research, which can be time consuming forthe user. Sometimes, some of the content may not be easily accessible.Indeed, the content may not be accessible at all. As a result, the usermay be distracted throughout the rest of the multimedia program, causingthe user to ignore portions that the producer believed were important orcritical to the user's experience with the program. Moreover, a user mayget distracted and lose interest in the multimedia program, costingbroadcasters and advertisers revenue dollars.

Embodiments of the present invention provide a system and method forpresenting interactive multimedia programs, where the user can interactwith the multimedia program to retrieve additional content associatedwith the multimedia program without interfering with presentation orenjoyment of the program. One aspect of the present invention providesfor presenting a multimedia program using a multi-channel transmission,where at least one channel is used for transmitting the multimediaprogram content and at least one other channel is used for transmittingthe additional content. Another aspect of the present invention providesfor providing the additional content to users on the basis of one ormore user queries, rather than prompting or otherwise forcing the userto view content he is not interested in.

FIG. 1 depicts an exemplary embodiment of a communications system 100supporting presentation of interactive multimedia programs according toembodiments of the present invention. As shown in FIG. 1, the system 100can comprise an interactive multimedia system (IMS) 102 for presentinginteractive multimedia programs. According to embodiments of the presentinvention, interactive multimedia programs can include any presentationof sounds, information, still images, moving images, or any combinationthereof. The IMS 102 can include a multimedia processing element (MP)120 for presenting these multimedia programs. Multimedia programs can beprovided to the IMS 102 using digital technologies, analog technologies,or any combination thereof. Furthermore, the multimedia programs caninclude, as previously noted, one or more channels of information. Forexample, a multi-channel digital television program can include a videochannel, an audio channel, a closed captioning channel, and one or moredata channels. In the embodiments of the present invention, an IMS 102can present the multimedia programs using media devices 104 such asaudio devices 104 a, video devices 104 b, computer units 104 c, or anycombination thereof. In some embodiments, the multimedia program can bepresented using multiple media devices 104.

The IMS 102 can receive interactive multimedia programs from a varietyof remote sources 106 a, 106 b, and/or local sources 108. Local sources108 can include devices such as audio/video consumer electronic devices(e.g., audio and video disc-based players, analog and digital video tapeplayers, phonographs, analog and digital audio tape players, MP3players, digital still and video cameras, and computing devices). Remotesources can include both wireline sources 106 a and wireless 106 bsources. For example, wireline 106 a sources can include Internetprotocol television (IPTV) subsystems, cable television (CATV)subsystems, wireline telephony networks, and wireline data networks.Wireless sources 106 b, for example, can include satellite televisionand radio subsystems, terrestrial television and radio broadcasts,wireless telephony networks, and wireless data networks. In the case ofa wireless source 106 b, an antenna element 107, such as an aerialantenna, satellite dish, or other reception hardware, can be used toreceive the multimedia program. One of ordinary skill in the art shouldappreciate that the invention is not limited to the aforementionedexamples and that local sources 108 and remote sources 106 a, 106 b canencompass any potential source of multi-channel multimedia programs.

As shown in FIG. 1, the IMS 102 can also include a command or queryprocessing element (QP) 122 for processing user commands and queries formanaging the IMS 102. One or more input devices can be provided forusers to input commands for managing the IMS 102. These input devices110 can be configured to communicate with the IMS 102 using wireline orwireless technologies. For example, input devices 110 can include awireless controller 111 using infrared or radio frequency (RF) signalsto wirelessly communicate with the IMS 102. The input devices 110 caninclude a wireline or wireless keyboard and/or pointing devices 112.Alternatively, the input device 110 can also include an audio input 113for accepting speech-based commands. In the various embodiments of thepresent invention, the type, configuration, and number of input devicesprovided for the IMS 102 can vary based on the types of users. Althougha single input device 110 can be used to manage the IMS 102, it is alsowithin the scope of the present invention to use a combination of inputdevices 110 to enter commands for managing the IMS 102. These exemplaryembodiments of input devices 110 are presented by way of example and notby way of limitation. Accordingly, it should be apparent to one ofordinary skill in the art that any type of input device can be used tomanage the IMS 102.

In the exemplary embodiment of the system 100 shown in FIG. 1, the IMS102, media devices 104, local sources 108, and antenna elements 107 areshown as distinct and separate elements. However, it is also within thescope of the present invention to incorporate the IMS 102 into anotherdevice. For example, the IMS 102 can be incorporated in a televisionset. In another example, the IMS 102 can be incorporated in a set-topbox (STB) for digital video recording or channel tuning. In yet anotherexample, the IMS 102 can be incorporated in an audio system.Accordingly, the IMS 102 can be incorporated in any device capable ofreceiving or presenting at least a portion of the multi-channelmultimedia program. For example, a typical home theatre system caninclude a television cooperatively coupled with a surround sound systemto present multimedia programs from a STB or a DVD player. In such anarrangement, the IMS 102 could be incorporated into the television, thesound system, or both.

FIG. 2 shows an exemplary method 200 operating in parts of system 100according to an embodiment of the present invention. In step 202 of theexemplary method 200, a multimedia program having one or more segmentscan be selected for transmission or presentation. The segments can bedefined by any type of division in the multimedia program. For example,a multimedia presentation may be divided into segments by time,topic(s), participant(s), location(s), or any combination thereof—toname a few. For example, a multimedia program regarding a number oflocations may be divided by location, but can also be further divided bytopics discussed at each location.

Once the segments for the multimedia program are identified in step 202,the multimedia programs or their segments can be classified according totheir content in step 204. Classification of the multimedia programs canbe necessary because different types of multimedia programs can includedifferent types of content that can affect the types of data that arelikely available for the program. For example, the type of contentassociated with sporting event can be different than that associatedwith a nature documentary or a news show. In the sporting event, contentcan include player, team, venue, and other sporting event informationand statistics. In contrast, the nature documentary content can includelocation, wildlife, plant life, and weather information. The presentinvention can also classify the various segments of the multimediaprogram. Such classifications can be necessary because even within asingle multimedia program, different portions can be presented indifferent formats. In some embodiments, the multimedia program segmentscan have separate classifications. In other embodiments, theclassifications for the various segments can be sub-classifications ofthe classification of the entire program. For example, the naturedocumentary can include, as previously discussed, narrative portions andinterview portions. Therefore, although each segment can be genericallyclassified as narrative and interview segments, alternatively thesegments can be classified into the sub-classifications of a naturedocumentary narrative segment and nature documentary interview segment.

Once the multimedia program or the segments therein have been classifiedin step 204, a data entry template for each classified segment can beretrieved in step 206 and a database for the multimedia program can begenerated in step 208. The data entry template can be used to generate adatabase of content likely to be associated with a segment of aparticular classification. Although the data entry templates can bestatic for each type of classification, in some embodiments, the dataentry templates, upon retrieval, can be further customized for aparticular media program or segment that includes other types ofcontent. A data entry template can be as simple as a listing of thetypes of content typically associated with a classification of segment.The listing can then be used to generate a database of content using adatabase application. In other embodiments, the data entry template caninstead be an empty database, ready to be populated with content.However, the data entry templates need not be provided separately andcan be included in a single database, where database includes thetemplate information sorted by segment.

Regardless of how the database is generated in step 208, the databasecan be populated in step 209. Entries for the database are not limitedto pieces of textual information, but can also include audio, videoand/or graphical information. For example, referring back to the naturedocumentary example, additional information on wildlife can includeimages (still or moving) or sounds of specific animals. However, thetypes of entries can also be limited by the type of multimedia program.For example, for an audio/video presentation, text, sounds, and imagescan be included. In contrast, entries for an audio program may belimited to only text and/or sounds, as a display device may not beavailable during playback of an audio program.

Using the database populated in step 209, a data stream for themultimedia program can then be generated in step 210. The stream caninclude all the content and identifying information for the content,based on the template, arranged according to the order of the segmentsin the program. The timing of the data stream can be configured tocoincide with the timing of the segments of the multimedia presentationas they are presented to the user. That is, as the multimedia programmoves from segment to segment, the content of the data stream can alsovary. For example, the data stream can be configured to provide acumulative source of content so that at any point in the multimediaprogram, the user will have access to any content previously available.However, the data stream can also be configured to include only contentrelevant to the current content of the multimedia presentation.Therefore, content not considered relevant to the content in currentsegment of the multimedia presentation is not included in the currentportion of the data stream.

Once the data stream is generated in step 210, a query grammar forinterpreting commands to access the data in the data stream can begenerated in step 212. It is to be noted that the term “grammar” is usedherein in a generic sense and pertains to any technologies that returnspeech-interpreted outputs. In human speech, for example, a grammarspecifies a relatively limited, finite number of ways to express athought. By contrast, a grammar, such as statistical grammar isconsiderably more robust, albeit typically computing- andmemory-intensive. Accordingly, the term grammar, as used herein, refersbroadly to all of the various types of grammars that can be used forrendering speech-interpreted outputs regardless of the underlyingtechnology utilized.

The query grammar can be used for responding to commands and queriesthat are input using the input devices 110. Such a configuration isadvantageous because using a grammar-based recognition of commands andqueries does not require the user to know a specific command or queryform for retrieving content. Instead, the user can input a command orquery using any type of format. The query grammar can then interpret thecommand and, if valid for the grammar, take the appropriate action. Thequery grammar can be generated based on the content and the data entrytemplates used to generate the data stream. Accordingly, only a limitedgrammar need be generated. By providing a limited grammar rather than afull grammar for recognizing any command to the IMS 102, the IMS 102 canbe configured to be responsive to commands regarding only availablecontent and prevent unnecessary searches for unavailable content duringa presentation of the multimedia content.

In some embodiments, a single query grammar can be generated for themultimedia program. However, because the content of different segmentsand the associated content can vary, a query grammar can be generatedfor each segment of the multimedia program. Regardless of how the querygrammar or grammars are generated, the generated grammar or grammars canbe included as a first portion of the data stream, presented prior tothe content that the grammar or grammars are based on.

One aspect of the present invention provides that a multimedia programis delivered in step 214 to the IMS 102, the program including a one ormore program content streams in one or more content channel channels, adata stream of additional content in a data channel, and associatedquery grammar(s) in a same or separate data channel. The IMS 102 canthen, in step 216, use the MP 120 to display the multimedia programcontent from content channels on a media device 104. The IMS 102 canalso, in step 218, retrieve the query grammar for the QP 122 and thecontent in the data stream. The IMS 102 can use a storage element tostore and access the query grammar and the additional content as needed.In the various embodiments, a pre-processor portion (not shown) of theIMS 102 can be used to determine what types of streams are located inthe various channels being received by the IMS 102. However, in someembodiments the pre-processing portion, or at least its functionality,can also be incorporated into the QP 122 or the MP 120. In otherembodiments, the channels can be standardized and the MP 120 and the QP122 can receive all channels and selectively choose the content and datastreams, respectively, according to the channel standard. Oncepresentation of the program begins, the QP 122 can then monitor for usercommands or queries in step 220.

Another aspect of the present invention provides that the query grammaris not provided to the IMS 102. Rather, the IMS 102 can be configured togenerate the query grammar as needed. Such a configuration isadvantageous in that the amount of data channels or data bandwidthneeded to deliver a multimedia program is reduced. In such embodiments,only the program content streams and data streams are delivered to theIMS 102 in step 222. As described before, the multimedia program contentcan then be presented in step 224, and the additional content in thedata stream can be stored in step 226. However, the QP 122 can beconfigured to generate a grammar based on the received data stream instep 228. Because the data stream inherently includes both the contentand the data entry template used to generate the data stream, the QP 122can be configured to extract the template from the data stream andgenerate the necessary query grammar, as previously described for step212. Furthermore, the query grammar can be generated by the QP 122 on aprogram basis or on a segment-by-segment basis. In a segment-by-segmentmethod, the query grammars can be generated at the beginning of thepresentation of each segment. However, it is also within the scope ofthe present invention to initially provide a “burst” of all information,including segment information, at the beginning of the presentation ofthe multimedia program to allow the QP 122 to generate all necessaryquery grammars. Afterwards, the QP 122 can monitor for user commands orqueries in step 220.

As previously described, one or more input devices 110 can be used toprovide input to the IMS 102. In some embodiments of the presentinvention, a speech-based input can be used. In other embodiments,commands can be provided to the IMS 102 using a wireless controller 111or a keyboard and/or pointing device 112. If the QP 122 does not detectany type of input in step 230, then the QP can continue to monitor foran input in step 220.

If the QP 122 does detect an input in step 230, then the QP 122 candetermine whether the input is associated with a valid command or queryfor retrieving content from the data stream. However, the manner inwhich commands are processed can vary depending on the way in whichinputs are processed. For example, in a speech-based system, the QP 122can be configured to convert all input speech using a speech-to-textsystem. Therefore, once the text of the input speech is available, theQP 122 can use the query grammar to determine whether the inputcorresponds to a valid command in step 232. If the command is determinedto be invalid in step 234, the QP 122 can continue to monitor for inputsin step 220. Such a configuration can be advantageous because the QP 122can be simplified by always requiring a text input. Thus the same inputinterface can be used to link the QP 122 to a speech-to-text processorand to a keyboard 112 or other text input interface.

However, in some embodiments the speech-to-text system can be includedin the QP 122. That is, the QP 122 can be configured to both recognizetext and afterwards determine if the speech defines a valid command. Inat least one embodiment, the query grammar can also be used as thespeech recognition grammar. Therefore, rather than recognizing all inputspeech, only speech that can be recognized using the query grammar isconsidered a valid input. Such a configuration is advantageous becausethe recognition and the determination of validity of the command can beaccomplished in a single step, as only valid speech commands will berecognized by the query grammar.

Once the QP 122 determines in step 234 that the input detectedcorresponds to a valid command, the QP 122, in step 236, can access amemory location for the additional content associated with the inputcommand recognized. Afterwards, in step 238, the QP 122 can retrieve thecontent and present the retrieved content to the user. That is, theretrieved content can be passed to the MP 120, which then outputs thecontent to a media devices 104. The format and arrangement of thepresented content can vary. In some embodiments, the MP 120 can beconfigured to present the content in one or more standard arrangements.However, the retrieved content itself can specify how the data is to bepresented. For example, the retrieved content can also includeinstructions for the MP 120 to display the data entries in a certainarrangement.

In other embodiments, the MP 120 can also be configured to determine howto best present the content based on the available capabilities of themedia devices 104. For example, if the MP 120 is presenting theretrieved content using an audio output device, the MP 120 can determinethat visual content should not be shown. Furthermore, the MP 120 candetermine that audio sounds will be required to present the content. Insuch embodiments, the MP 120 can include a text-to-speech system tooutput textual content in a spoken format. The spoken text can then beoutput as additional sounds during the playback of the audio program.Similarly, the MP 120 can determine that content that includes a highresolution image needs to be converted to a lower resolution image whena high resolution display is unavailable. In some embodiments, theretrieved data can also specify how to present the content for differenttypes of output devices.

In yet other embodiments, the MP 120 can also be configured to determinewhether not to alter presentation of the original program. For example,although additional content can be presented as a voiceover during aplayback of an opera or orchestral piece, providing a voiceover during arecording of a conversation can easily confuse the listener. In suchembodiments, the MP 120 can be configured to determine that if asubstantial overlap exists between the voiceover and the originalsounds, the volume of the original program should be reduced so that thespeech can be used as a proper voiceover. In some cases, instead ofreducing volume, the original program can be presented, for example,using only one of two available audio loudspeakers and the voiceover canbe presented using the other loudspeakers. In another example, althoughvisual content can be shown in a small area of a display output device,the visual content may be of a nature that cannot be adequately shown inthe small area. Instead, the MP 120 can reduce the size of the originalprogram and use a larger portion of the display output device to displaythe visual content. Additionally, instructions for altering thepresentation of the original program can be included with the data. Suchembodiments can be advantageous as the amount of processing required bythe MP 120 can be reduced.

Although the exemplary embodiments described above provide examplesshowing the retrieval of additional content from the data stream only,the invention is not limited in this regard. In some embodiments, priorto retrieving and presenting additional content in step 238, the QP 122can also be configured to determine whether updated content exists. Forexample, in a live sporting event information is constantly beingupdated. Scores, statistics, penalties, and other values changethroughout the event. In such embodiments, the QP 122 can be configuredto access one or more remote servers via a data network to retrieveupdated information. In some cases, the content in the data stream caninclude not only the content available at the time of generating thestream, but can also include one or more locations for obtaining updatedcontent. Therefore, the QP 122 can determine in step 240 whether anyupdated content exists for the data stream and retrieve and present thiscontent in step 240.

In some embodiments, the content can be updated only once or after aninterval of time has elapsed. In other embodiments, the information canbe updated when uploaded to the IMS 102 or only when the content isrequested by a user query. Accordingly, the IMS 102 can be configured toprovide a system for updating the content that is most efficient for thetype of content being updated and the network capabilities of the IMS102. Once the content has been presented in step 238, the IMS 102 candetermine if another segment has started in step 242. If not, the IMS102 can continue monitoring for inputs and responsively outputtingcontent as in steps 220 and 230-238. If a new segment is started, theprocessing for the segment starting with steps 212 or 222 can berepeated.
